authorities. The double Isaac has a nominal capacity of 66 kg. of ice per day. Measurements in Maruata
made in November-December 1994 showed an average ice production of 29 kg. per day per unit. The cold
storage had an average temperature of 5 oC during these months, which is quite adequate for short time
preservation of fish. The village at the time of installation had no electricity but now it has. It is imperative
to have a good supervision and maintenance of the system in order to have the system operational so that it
can survive the temptation of changing them for a conventional unit. In February 1998 a visit to the
Maruata installation confirmed that at that time the system was not operating due to a lack of maintenance
and proper handling.
